The M ixe r
As one would expect, the main pu rpose of the mixer is to
combine sounds, but under precise and smooth control. This
is why long-th row fa ders a re essen tial on any p rofession al
product. The faders provid e you with clear and instinctive
control of the final sound balance and like an artist playing an
instrument you sh ould listen to the effect of your fader
movements, not look at your hands.
You r SPIRIT LIVE 4 mixer accepts a wide range of input
signals via a microphone input, for very low level signals, or a
line inp ut, for h igher lev el signals fr om, for ins tance, tap e
mach ines, effect s pro cessors , etc.
The mixer is split in t o two sect io ns. The Inputs receive, m atch
and pr ocess ind ividu al sou rce signa ls, and distr ibute t hem at
precise mix levels to either a ster eo Mix outpu t or to one of
the Groups. The Master section allows over all lev el con trol
of all outputs, and provides monitoring of the audio signal at
man y poin ts in t he m ixer, eith er on head pho nes or mete rs.
The Equaliser controls are th e mo st flexible a nd p oten tially
destructive featu re of the mixer. They have a sim ilar effect on
the frequency response of the input chann el as the tone
controls on a hi-fi system, but with much greater precision,
and allow particular characteristics of the input signal to be
emphasised or reduced. It is very important that you become
familiar with the effect each control has on the sound an d this
is best achieved by spen ding time listenin g to the effect of each
control on a well-known track played through the mixer.
The Auxiliary Sends prov ide a wa y of rout ing the in put
signals to a number of secondary outputs, for artists foldback,
echo units or additional speaker outpu ts.
The Pan control adjusts the position of the input signal w ithin
the stereo mix, and can be swept from full left, through to full
right. This allows particular artists to retain their correct
spatial position within the mix, and can be valuable for live
effects.
Pre-Fade-Listen(PFL) allows you to monitor the signal at
many points in the mixer. Pressing any PFL switch places the
signal at that particular point onto the headphones and the
right meter, to check the quality of the signal or to pin-point
problems. Using PFL will not affect the signals on the outputs
from t he d esk.
